Extracts data from Hive and sends the data to the component that follows.
tHiveInput is the dedicated component to the Hive database (the Hive data warehouse system). It can execute a given HiveQL query in order to extract the data from Hive.
When ACID is enabled on the Hive side, a Spark Job cannot delete or update a table and unless data is compacted, this Job cannot correctly read aggregated data from a Hive table, either. This is a known limitation described in the Spark bug tracking system: https://issues.apache.org/jira/browse/SPARK-15348.
